I used Epic All in One Root and Recovery v2.04 a while back to root my Epic. Uninstalled a few of the apps. Got the froyo push today but it wouldn't take, figure it had to do with removing apps and rooting. I recovered the apps and removed root. Downloaded the update.zip and booted into recovery mode to install. I'm now getting an assertion error because the install cannot find /system/bin/playlogo

I've read some threads and noticed some of the root procedures created a playlogo-orig. I don't have that file. I do have playlogos1 though, though I'm guessing that isn't the same file?

Sort of stuck on what to do next. Can't seem to locate a playlogo to download to sdcard. Any help would be appreciated.
[Epic 4G General] Esteway.619:
Just use Odin to flash back to stock
[Epic 4G General] skeeterslint:
You are correct playlogos1 is not the same file as playlogo.The one click root should backup playlogo since it still gets run by the script that replaces playlogo it just runs playlogo-orig from the script that is named playlogo that one click installs.
[Epic 4G General] deflin39:
Thanks for the info. I'll give Odin a shot.
[HTC Inspire 4G] Verysafety:
So I'm wondering to myself (having used other phones like the Captivate)

While on a call, the actual call quality is fine. When you are setting other tunes on the phone though, such as system sounds or text messaging noises, they aren't there (this happened to me on stock before I flashed anything). Also, the sound would play really loud through the ear speaker piece on the phone, rather than the speaker on the back of the phone.

They have output all system sounds to the speaker, right? And the sound doesn't sound low quality, but...

Maybe I'm confusing everything, I realize the "sound fixes" people post do fix the sound quality, but what about the sound output (ability to ouput more than one type of sound like I described above)

Or is there no way to really design this the way I described?
[HTC Inspire 4G] RMSublime12:
How do I do it? I just gave up and restored the phone to factory settings and formatted the gold card. but how do I get my sound back? And United States English o_O
[HTC Inspire 4G] tribalartgod:
Did you downgrade at all?

What files did you use to "get back to stock"?

What is your current software version?

There needs to be more info provided please. The more specific info you can give us, the easier it will be to resolve your issue. :-)

[KERNEL][CM7][Froyo] Dalingrin's OC kernel w/fixed IO perf (quadrant) & 1.2Ghz test

Disclaimer: As always, flash at your own risk.

Background

So, recently there has been alot of debate over why quadrant (and to some extent, system performance) was lower with the OC kernel, as compared to the stock CM7 kernel. (http://xdaforums.com/showthread.php?t=1002504) As part of my examining the problem, i went looking for a solution. Starting from the first OC CM7 kernel, i would run quadrant and see how the performance fared. I finally found the issue appeared in the 3-08a kernel; using that, i rolled back changes until i found the commit remove to fix the issue. Specifically, it seems to be somewhere in the 2.6.29.6 update: https://github.com/dalingrin/nook_kernel/commits/gingerbread-exp

In short, using his source, i have compiled a kernel with fixed I/O performance, and all his other tweaks (interactive gov, etc).

So, I want to make this clear; this is still dalingrin's kernel; in no way do i wish to take credit for his work. But, while he is out, work must go on, right?

Information

Who is this kernel for?

eMMC Froyo and CM7 users

Will this work on SD cards?

It may if you manually replace you uImage, but i cannot guarantee it (since i cannot test it)

Is everything working in this release?

everything like bluetooth and dsp should still be just fine (you may have to do a few hard shutdowns/reboots to kick on BT, like normal).

Kernel Links -3/25/10

OC kernels (up to 1100Mhz, Interactive gov, BT and DSP):

Regular

http://www.mediafire.com/?k00ruvyulf01y64

Extra network features (PPP, etc)

http://www.mediafire.com/?i9h76wn483tk16v

OC kernel (up to 1190Mhz, Interactive gov, BT and DSP):

http://www.mediafire.com/?v6d2jpzaynvchde

For those having problems setting this speed in the CM7 performance settings, give setCPU a try, but don't use profiles. Using set CPU, i am able to get my system stable at 1190, where the CM7 manager instantly locks up.

Feedback

After flashing, please make note of OVERALL system response. The dip in quadrant scores prompted the fix, but i feel that the system is overall better; I would like some more input if others are seeing this as well.

Any and all feedback is welcome, and I will do what i can for support...
[Nook Color Android Development] Nburnes:
Great job man, you and dalingrin both!

Ran 3 quadrant tests on newest nightly (#30)

1. 1856

2. 1700 even

3. Whopping 2030!
[Nook Color Android Development] ADude:
Can you be more specific about which network features are in the second choice ?

Thanks !!
[Nook Color Android Development] Divine_Madcat:
Um....truth is, i am really not too familiar with it, but looking a the diff between the two configs:

# Core Netfilter Configuration

# IP: Netfilter Configuration

# CONFIG_TUN

# CONFIG_PPP

I am trying out the net kernel again, to see if it is better than the last time i tried it..

Edit: Its looking better than the last time i tried it. Launcher pro hangs for a but on startup, but so far so good after that.
[Nook Color Android Development] 360Razir:
Just started using CM7 last night (w/bottom keys mod, so the nightly is from a few revisions back), but just installed this kernel (the regular version, w/out the Net adds, which I don't need), wiped cache & Dalvik, rebooted, set OC to 1100 and "performance" in CyangenMod Settings and now getting 1918 Quad score...vs. 1372 on the stock kernel with no OC.

I can definitely live with that score...great work to you and dalingrin!!
[Nook Color Android Development] dalingrin:
Thanks for taking care of this while I am gone. Much appreciated.

The update to *.6 is not necessary anyway.

When I get back I will revert the *.6 update and compile some of the netfilter/iptables and tun as modules as this seems to be more compatible than compiling them directly into the kernel.
[Nook Color Android Development] moonpie28:
Madcat, kudos to you. This is perceptibly faster.
[Nook Color Android Development] dalamchops:
great work!
[Nook Color Android Development] hazridi:
so is this a 2.6.29.5 kernel then?
[Nook Color Android Development] dalamchops:
WOW, scrolling through XDA forum is much smoother than it used to be.
[Nook Color Android Development] Homer_S_xda:
Tried on SDcard, installed by copying uImage to Boot. Reboots to EMMC when trying to load desktop. Back to CM7 stock. I guess I'll wait. Thanks though!

Homer
[Nook Color Android Development] chisleu:
Can I have the config file for the first? I'm going to play with the kernel a bit.

EDIT: I'm just going to keep my big mouth shut for a while. I hoped it was just a bug with quadrant, but I flashed your kernel just now. There is a huge difference in interactivity. I was playing with the app drawer yesterday and couldn't get it to be smooth with "labels fade in" turned on and a 1000ms or so time on the animation for the app drawer. Now it's perfect every time.

GOOD JOB! :)
[Nook Color Android Development] marlonbr:
I love Open Source.

Will try this in some minutes. (Nook charging)

Ok, tested it. My scores below.

** QUADRANT SCORES **

Before update, 1100mhz: ~700

After update, 800mhz: ~1500

Now, 1100mhz: 1920

**********************

Awesome!
[Nook Color Android Development] eghill1125:
Just flashed it on mine and seems silky smooth to me. Not real sure there is a big difference, but it is not worse at least. Seems better to me.. Good job Madcat!!

Waiting anxiously for Dalingrin to return to his lab and see what else he can whip up for us.. :)
[Nook Color Android Development] barrist:
nice!

i'm getting the same numbers as others (~1800) now. haven't really tested for overall smoothness yet.
[Nook Color Android Development] cowballz69:
will this kernel ever get a nookie version?
[Nook Color Android Development] Divine_Madcat:
I have to admit - i said CM7 only, since that is all i have to test it on. If you do want to try it, you don't really risk anything; if it doesn't work, simply reboot to recovery and flash your last working kernel again.

As it is, i haven't really given a good look at what might be different between versions, so i can't give much advice on why it would/wouldn't work on Froyo.
[Nook Color Android Development] victle:
Got the same issue with the Net feature kernel. However the other one works fine. Got 1918 Quadrant on SD Card with OC 1100 GHz + interactive gov.

So I guess CM7 performance on SD is not too bad compared to eMMC :)

@Divine_Madcat : Could you look into the problem of the Net features kernel with SD Card booting? It run into eMMC after the bootanimation.

Thanks much for your work, an action is much better than thousand words !!
[Nook Color Android Development] SCWells72:
I tried both of these from SD card. The non-net features version boots but posted some terrible #s for me (<700 Quadrant and ~6-7 Linpack); the net features version doesn't boot. Is there something special I need to do with the first kernel to see the benefits? I checked and was clocked to 1.1GHz in CM settings.
[Nook Color Android Development] Divine_Madcat:
Ill be happy to take a look, but can't promise anything right away. ;)

hmmmm.. that doesn't sound right at all. May i ask which nightly you are using? Right now, i am on nightly 27, and haven't seen anything like that (in my case, it either works, or just boot loops, if i set the clock too high).
[Nook Color Android Development] victle:
Mine on SD Card, CM7 #30

@1100 GHz got 1918 Quadrant; 14.01 Linpack

@800 MHz got 1347 Quadrant; 10.709 Linpack

[Nook Color Android Development] cowballz69:
Woeks beautifully with nookie, thaks mate
[Nook Color Android Development] OverDrive33:
Very nice. Went from a Quadrant score of 1050-1200 to now seeing 1300 - 1500. I'm using Phiremod 5.1.

Linpack seems largely unchanged - hovering around 10-11 MFLOPS.

*EDIT* -- Whoops! Had it set at 800Mhz! Wasn't using the full 1100mhz! Linpack now see 13.8 MFLOPS and Quadrant up around 1800-2000!!

Went to use the app "Shoot Me" to save my screen shots ... it only saves blank pngs. *doh*.

Any hopes for better battery life using this kernel?
[Nook Color Android Development] ADude:
What are people using to set OC to 1100 ?

There have been numerous warnings in various threads - "Don't use SetCPU with CM7".

Thanks !
[Nook Color Android Development] funcrusher:
I think the issue is using SetCPU profiles with CM7, not just using it to OC.
[Nook Color Android Development] funcrusher:
Word? I may have to try this then.

[Nook Color Android Development] ADude:
Thanks and it is working fine on uSD card version of CM7 Nightly 25.

Firefox and Youtube App work fine.

BTW, is there any way - while running CM7 - to verify the installed Kernel version ?

The install process verified completion, but I could imagine at some point in all this testing, forgetting which one I had last installed. ;)

The Settings shows the overall CM7 version, but not the Kernel version.
[Nook Color Android Development] Divine_Madcat:
The "non net" version should be - 2.6.29-omap1 madcat@madcat-VirtualBox #2; i think the net version should be the same, but listed as #3.

unfourtunantly dolphin hd doesnt like this kernel on nookie rom, keeps force closing even after reinstall,dalvik wipe and cache wipe, opera works though but i dont like it anymore.scrolling is fast but scrolling text is to jittery for me
[Nook Color Android Development] eespiritu:
Just installed the new kernel with phiremod 5.1. I need to give it more time for real-time testing, but just ran 3 quadrant and Linpack benchmarks.

Quadrant testing

#1-1916

#2-2236

#3-2230

(Huge boosts in I/O performance)

Linpack testing

#1-13.9

#2-14.026

#3-14.125

(2-3 Mflop boost)

No problems with the install, I'll try to keep updating real time performance. Thanks to you and Dalingrin. You're awesome!
[Nook Color Android Development] ADude:
Is there somewhere on the running NC that lists this ?
[Nook Color Android Development] Divine_Madcat:
Yes - Settings -> About Tablet -> Kernel Version (you may have to scroll to see the "About Tablet" selection).
[Nook Color Android Development] Divine_Madcat:
For any crazies out there, i have uploaded a 1.2ghz (1190Mhz actual) rom . I will not make any guarantees on it, but it is fun to see if your nook will run 400Mhz faster than stock. ;)

[Nook Color Android Development] scubageek01:
Not sure why, but I started getting boot loops after applying the new kernel.
[Nook Color Android Development] barrist:
tempting. hah.

is there a stress test out there we can use to test this?
[Nook Color Android Development] Divine_Madcat:
Anything like a few runs of Quadrant should expose any issues. Otherwise, regular use is the best test. If you see alot of force closes, you know something is up....
[Nook Color Android Development] Jiggity Janx:
I'm game for giving this a try. I've been using DroidX/2 Overclock on my DroidX (same cpu/gpu) at 1.35 for about 6 months now. I don't do anything crazy intensive usually and have overall found it easily reliable.

Wifi cycling on/off with this

I installed this and it worked great for a little while. I got a Quandrant score >1,900 three times. Then I rebooted and it went all wonky.

Wifi's going on/off for while now, so I've rebooted it several times with no change. Going back to Dalingrin's OC kernel. Nice try, keep up the good work!
[Nook Color Android Development] chisleu:
I've been running it all day and it has been fine. I powered off the nook because the battery got down to 5% (forgot to charge it last night) and now I'm waiting on it to charge enough to boot up.

Can I get the kernel config file you made w/ menuconfig or whatever so I can get kernel compilation going and dive into the omap audio code?
[Nook Color Android Development] Divine_Madcat:
Just fair warning, the wifi bug is in the other kernels as well; its source had not been found yet.

The non net kernel is made with omap3621_nookcolor_defconfig, and the larger net kernel is made with omap3621_dalingrin_defconfig
[Nook Color Android Development] wpnyc2009:
Thanks for the update on WIFI issues

I appreciate the feedback. I've never had wifi issues on any other kernel (stock or custom) so I might have paniced too quickly. :)

Cheers m8!
[Nook Color Android Development] ADude:
You should remove this post and create a separate thread.

Every following post says "I installed it and..."

We no longer know whether "it" is the 1.2ghz kernel or your fix of the 1100 kernel...
[Nook Color Android Development] rocklobster702:
Net Version

Question... would the net version theoretically enable IPTables (for proxy usage) or am I holding my breath about that for nothing?
[Nook Color Android Development] MedLine:
I'm in, flashed it over CM7 n30. Booted up no problem, overclocked to 1190MHz interactive governor, scrolled around a few screens, no problem, then ran Quandrant SE five times (max score 2193), still no lockup.

I'll use it a little bit more later and get better sense of stability but so far so good.
[Nook Color Android Development] barrist:
hmm just tried the 1.2 ghz kernel, just tried to select the speed in cm7 settings but it froze the whole thing. had to shut down..

will give it another shot after rebooting.
[Nook Color Android Development] Divine_Madcat:
Eh.. i dont think it is a huge deal, seeing that the 1.2Ghz IS the 1.1Ghz kernel, just with a change clock speed table. Otherwise, the build is identical.

Unless they were already in Dalingrin's kernel, don't expect them here. This buildis based on his work, with some fixes to the kernel; no new additions (yet. ;))

Awesome! 2193 is just insane; i am glad to hear its working for you, since....

... this is exactly what happens to me as well.. :(
[Nook Color Android Development] rocklobster702:
Dalingrin lists the feature added to one of the recent kernel updates, but I've yet to see any functionality from it.
[Nook Color Android Development] Divine_Madcat:
Well, all i can say, I only did some bug fixing; no other changes. If it didn't work in the original, i think it is safe to err on the side of caution, and assume the same here. Sorry about that. :(

EDIT: So, this is really wierd. Using the CM settings, 1190Mhz instantly locks my system up. HOWEVER, if i use SetCPU, it runs just fine, and makes several complete benches at 1190...... I can't explain this one, but it is something to try (and i will update the first post with this).
[Nook Color Android Development] barrist:
Hmm well maybe its just my nook but did not react well with the 1.2 kernel. First locked up when I set it to 1190 in the settings. Rebooted and then touchscreen wasn't responding.

Any suggestions
[Nook Color Android Development] Divine_Madcat:
Yes (sorry if this is an annoying proceedure, but will help get you stable(er)):

Reflash the 1100 Kernel of you choice, so that CM settings gets reset.

Reflash the 1200 Kernel.

Install SetCPU: http://xdaforums.com/showthread.php?t=505419

Using ONLY the clockspeed setting portion (NO profiles!!), set your clockspeed to 1190

I did the same on mine, and now i can bench and game at 1190 stable, where the CM7 settings would just hardlock. I can't promise it will fix your case, but it cannot hurt to try.
[Nook Color Android Development] MedLine:
Well that was fun while it lasted. Picked up the NC after an hour of "sleep" and got past lock screen no problem. Opened up QuickPic, at 1190MHz the folder thumbnails never flew by so quickly (I've got 11000 JPEG, about 250Kb each, spread across 94 folders in the eMMC mount). Next checked eMail, it's been syncing with Exchange server OK (wireless set to never sleep). But then fired up Opera Mobile 11, and touchscreen response started acting wonky. Force killed Opera a few times, same touchscreen behavior and pages never finished loading.

Nothing actually froze, so I rebooted. First two attempts locked up prior to lockscreen. Third attempt got past lock-screen but locked up again before I could get to Settings to dial back to 1100MHz. At that point I got out CWR 3.0.1.0 SD, booted into recovery, flashed back to madcat-032511, after which NC booted up no problem. Went into Setting/CyanogenMod/Performance and found clock speed defaulted back to 800MHz, promptly overclocked it back to 1100 MHz, and just now ran Quadrant SE three times and got best score 1966.

I guess 1100MHz is best stable overclock for my NC :(.
[Nook Color Android Development] violinbf:
Running this at 1190mhz and seems stable so far! Getting about 2000 on quadrant. Bravo! I was having problems with on the old kernel from dalingrin and this works well for me. Thanks.
[Nook Color Android Development] krweby:
The non net version works fine. The net version boot loops. I've download it twice cleared cache and dalvik. Same problem. Went back to the non net version.
[Nook Color Android Development] Divine_Madcat:
MedLine - if you still feel like trying again, i posted a suggestion on using SetCPU; it allowed me to actually set the device to 1190, where CM7 settings would love. Perhaps setting it through SetCPU would net more stability?

:( Didn't work on my Nookie

I tried both the regular fix and the max oc fix kernel on my Nookie Froyo and both ended up boot looping after clearing cache and rebooting. Reverted to Dalingrin 2.25.11 OC kernel. :( Very jealous of the CM7 quadrant numbers.

1. go to cyanogen settings->performance->cpu->set interactive 800/800

3. install "1.2"

4. reboot

5. install Setcpu

6. Set Setcpu interactive, min 600 max 1190.

7. launch quadrand

Thank you very much both of you for the results.

On CM7 sdcard class 4, with the 1.1 kernel, getting consistently over 1870 quadrant.

This is big fun.

Noticed an improvement in speed and smothness. Even the video choppieness was fast, but still choppy, the choppy part was faster, lol.

I did notice that the screen seemed a bit less sensitive and the problems around the edges had returned.

Thanks for your time and work guys!

While I don't noticed any perceived difference from the 3/16 kernel, my quadrant scores practically doubled.

This was only on the 1.1ghz kernel, haven't had time to try the 1.2 kernel yet!

Great work Madcat!
[Nook Color Android Development] chisleu:
What are your settings to get such high results? Did you change memory compression or anything else?
[Nook Color Android Development] Nooter:
Running Phiremod 5.1, I was careful to uncheck "set on boot" in both setCpu and Cyanogenmod settings.

Madcat's OC kernel:

1190 - Consistently locks on set in setCpu 2.1.1a

1100 - Consistently locks when starting full benchmark in Quadrant Standard; random reboots

800 - Stable, smoother than stock CM7 kernel; Quadrant: 1363

Madcat's regular kernel exhibited some weirdness, though:

1100 - Quadrant: 1088 (locked up twice, ran successfully the third time and then locked up on the results screen)

1000 - Quadrant: 1585

Don't know what's going on here with the regular kernel/1100 setting. I will stick with the regular kernel/1000 setting, though!
[Nook Color Android Development] RileyGrant:

[Nook Color Android Development] ADude:
I think that the 1.2ghz has invoked the "my numbers are bigger than your numbers" instinct. ;) :D

Meanwhile I find that 1100 results eventually in FC's, so I am trying 1000 now.

BTW, I am wondering whether the very nice protective Silicone Skin that I use on my NC, is also thermally insulating the case and thereby insulating, rather than cooling the CPU (which, of course, has no fan or heat sink). Any thoughts ??
[Nook Color Android Development] chisleu:
I am not personally having any FC's at 1100.

I also don't have any heat coming off my nook.
